Doesn't say where this took place, which industry rejected her, or perhaps most importantly the position she was interviewed for. At 29 years old, it's probably safe to say that she's been in the job market for at least 3 to 5 years, depending on her degree. What has she been doing in the mean time? Some industries consider marriage and having a child as an indication of stability and commitment; an often desired quality in a job candidate for a professional position. However, most HR departments would use other criteria to determine that, such as past work history, particularly in an older job candidate. Discriminatory? On the surface and as a reason, yes. That definitely wouldn't legally fly in the US with anti-discrimination employment laws. At least she wasn't rejected for her skin, hair or eye color.
